Circumference of a circle = 2*pi*radius or pi*diameter
8
125.6 feet
Work it out the circumfrance of a circle is pie x the diameter!
circumference = 2*pi*5
Diameter is the distance across a circle. The circumference of a circle is the distance around the outside of the circle.
Formula to find the circumfrance of a circle~(2)(3.14)r or (3.14)d
the circumference of a circle is the length around the outer edge. and you find it by using the formula 2 times pi times the radius of the circle
it is the circumfrance of a circle divided by pi.
If the circumference (not circumfrance) is 31.4, the radius is 4.9975 units (to 4 dp).

125.6 feet
The diameter should be 7m.
Work it out the circumfrance of a circle is pie x the diameter!
circumference = 2*pi*5
Diameter is the distance across a circle. The circumference of a circle is the distance around the outside of the circle.
multiply the radius by two then pultiply that by pi
